The following aspects should be paid attention to when making electrical cabinet:

1. Design planning

1. Clear functional requirements: Before the design, it is necessary to clearly understand the functions to be achieved by the electrical cabinet, including the controlled equipment, working environment, load type and size. For example, for the control of high-power equipment, the heat dissipation design of the electrical cabinet is particularly important.

2. Reasonable space layout: Ensure that the layout of internal components is reasonable, easy to install, maintain and overhaul. A sufficient safe distance should be maintained between the components to avoid mutual interference. For example, strong and weak current components should be arranged separately to reduce electromagnetic interference.

Second, material selection

1. Cabinet material: should have good mechanical strength, corrosion resistance and protection performance. Common stainless steel, cold rolled steel and so on.

2. Insulation materials: used to isolate conductors to ensure electrical safety, to choose high-quality insulation materials that meet standards.

3. Selection of electrical components

1. Reliable quality: Select well-known brands and certified components to ensure stable performance and reliability.

2. Specification matching: the parameters of the components, such as voltage, current, power, etc., must be matched with the actual use needs. For example, when selecting a contactor, its rated current should be greater than the load current.

Wiring and wiring

1. Neat wiring: The line should be regular and orderly, avoid crossing and confusion, in order to facilitate heat dissipation and troubleshooting.

2. Secure wiring: Ensure that the wiring terminals are firmly connected and in good contact to prevent heat and failure caused by loosening.

5. Grounding and lightning protection

1. Good grounding: Ensure that the cabinet and internal components are reliably grounded to ensure personal safety and normal operation of the equipment.

2. Lightning protection measures: Install lightning protection devices such as lightning arresters in necessary positions to prevent lightning damage to the electric cabinet.

6. Heat dissipation and ventilation

1. Reasonable heat dissipation: According to the heating situation of the components in the electrical cabinet, design a suitable heat dissipation mode, such as installing fans, radiators, etc.

2. Good ventilation: ensure that the cabinet has enough ventilation holes to make the air flow smooth.

7. Identification and labeling

1. Clear identification: clear identification of each component and line for easy identification and operation.

2. Complete label: includes component name, model, parameters, wiring position and other information.

8. Testing and inspection

1. Electrical performance test: After the production is completed, electrical performance test, such as insulation resistance test, voltage resistance test, etc.

2. Functional test: Verify whether the functions of the electrical cabinet meet the design requirements.

In short, the production of electrical cabinet needs to strictly follow the relevant standards and specifications, pay attention to every detail to ensure its safe, reliable and stable operation.
